I have an android/ios app built with hotwire adapter (based on the [demo](https://github.com/hotwired/turbo-android/tree/main/demo) app). How can I serve different views for it from my web app? I want to make sure that the views for the browser on mobile browser is different to the views served to my mobile app.

If you’re using Rails, you could use [variants](https://guides.rubyonrails.org/layouts_and_rendering.html#the-variants-option) that are based on the request’s user agent. It looks like the demo app will send requests with the user agent ` "Turbo Native iOS"`. ([Defined here.](https://github.com/hotwired/turbo-ios/blob/ca008e8215c66c2a276862375709b5c819b8b8b8/Demo/SceneController.swift#L118))

Some pseudo-code for this idea might look like:

```ruby
class ApplicationController < ActionController::Base
  before_action :determine_variant

  private

  def determine_variant
    request.variant = :ios if request.user_agent.includes?("Turbo Native iOS")
  end
end

```

If you’re not on Rails, the same idea of switching on the user agent string would still be possible.
